CVE-2024-57899

CVE-2024-57899 affects the Linux kernel’s wifi/mac80211 code. On 32‑bit systems, the code uses or_each_set_bit(bit, &bits, sizeof(changed) * BITS_PER_BYTE) where an 8‑byte u64 is accessed as a 4‑byte unsigned long, causing incorrect bit searches and potential flag corruption in MBSS changes. The ...
